At-a-glance: Post-apocalyptic underwater • d6 dice pool • 2–5 + GM • Low-to-moderate prep • Medium complexity • 2–4h sessions

Theme and Setting

Polaris takes place centuries after wars and climate catastrophe rendered Earth's surface uninhabitable. Humanity sought refuge beneath the swollen oceans, guided by mysterious benefactors known as the Geneticians. Now survivors cling to existence in underwater settlements called Havens, struggling with genetic degeneration, perpetual faction wars, and monsters of the deep. The world combines sleek underwater aesthetics with brutal survival stakes—society teeters between rebuilding civilization and collapsing into barbarism.

Core Mechanics and Rules

The system uses a d6 dice pool mechanic where players roll attribute dice plus skill dice, counting successes. Combat is tactical without being overwhelming, with hit locations, armor values, and weapon variety. Character creation offers four genetic types: normal Humans, Natural Hybrids, Geno-Hybrids, and Techno-Hybrids—each with distinct underwater survival capabilities. The game emphasizes resource scarcity, equipment condition, and the constant threat of drowning or pressure failure.

What Makes It Unique

Polaris stands out through its distinctive underwater post-apocalyptic setting that avoids Waterworld clichés. The French design sensibility brings a different flavor to survival gameplay—elegant robes and advanced technology contrast with desperate scavenging. The genetic modification system lets players breathe underwater and survive crushing depths, but at the cost of human identity. Faction politics between Haven cities add social intrigue to survival scenarios, while sea monsters and ancient ruins provide exploration hooks.

Target Audience and Player Experience

Ideal for groups seeking survival-focused sci-fi with tactical depth and unique aesthetics. Fans of Dune, The Hunt for Red October, and underwater exploration will find familiar touchstones. The system accommodates both narrative-focused and mechanically-inclined players, with enough crunch to satisfy simulationists while remaining accessible. Expect campaigns about scarce resources, faction loyalty tests, and the psychological toll of living in the crushing dark—where every expedition risks decompression, mutation, or worse.
